 ...ERN NEW ENGLAND TO MID ATLC...   WIDELY SCATTERED TSTMS IN MIXED MODE OF DISCRETE...CLUSTERED AND   SMALL BANDS SHOULD FORM THROUGH EVENING AHEAD OF COLD FRONT...MOVING   EWD TO NEWD INTO INCREASINGLY MOIST AIR MASS WITH PROXIMITY TO ATLC   COAST.  MOST INTENSE TSTMS WILL BE CAPABLE OF SVR GUSTS AND SPORADIC   LARGE HAIL.   GIVEN PASSAGE OF EXTENSIVE CONVECTION ACROSS PARTS OF NJ...LONG   ISLAND AND SRN NEW ENGLAND ALREADY THIS MORNING...AIR-MASS RECOVERY   AND DENSITY OF SUBSEQUENT DEVELOPMENT ARE UNCERTAIN ACROSS THOSE   AREAS CURRENTLY LEFT INSIDE ASSOCIATED OUTFLOW POOLS.  RELATIVE MIN   IN CONVECTIVE COVERAGE MAY BE NOTED FOR MUCH OF TODAY IN PARTS OF   THAT CORRIDOR.  HOWEVER...LOW-LEVEL THETAE ADVECTION AND SFC   INSOLATION THIS AFTN STILL MAY CONTRIBUTE TO FAVORABLE   DESTABILIZATION...WITH ADDITIONAL LOW-LEVEL FORCING POSSIBLE ALONG   RESIDUAL OUTFLOW/DIFFERENTIAL-HEATING BOUNDARIES.  ONE SUCH BOUNDARY   -- CURRENTLY LOCATED OVER PARTS OF DE AND MD ON EITHER SIDE OF   CHESAPEAKE BAY...MAY LIFT NWD ACROSS DELMARVA/SRN NJ AND CHESAPEAKE   BAY AREA.   SFC THETAE IS EXPECTED TO STRENGTHEN WITH SWD EXTENT ACROSS ERN MID   ATLC...WHILE WINDS ALOFT...HEIGHT FALLS AND DEEP SHEAR EACH INCREASE   NWD.  MLCAPE SHOULD RANGE FROM AROUND 500 J/KG OVER PARTS OF NERN   MAINE WHERE LOW-LEVEL MOISTURE IS WEAKER...AND ALSO IN MOST STRONGLY   STABILIZED POST-OUTFLOW AREAS FARTHER S...TO AROUND 2500 J/KG NEAR   AFOREMENTIONED OUTFLOW BOUNDARY AND PORTIONS COASTAL MID ATLC.    EFFECTIVE-SHEAR MAGNITUDES SHOULD RANGE FROM ABOUT 25-35 KT OVER   CENTRAL/SERN VA TO 50 KT OVER PARTS OF MID ATLC AND NEW   ENGLAND...BUT NOT NECESSARILY WHERE CAPE IS GREATEST.  STILL...WINDS   ALOFT SHOULD BE ALIGNED NEARLY PARALLEL TO OUTFLOW BOUNDARY...AND   BENEATH RELATIVELY STEEP MIDLEVEL LAPSE RATES AND RESIDUAL EML   SAMPLED BY MORNING WAL RAOB.  AS SUCH...MESOBETA- TO LOCAL-SCALE   ENHANCEMENT TO SVR POTENTIAL INCLUDING SUPERCELL/TORNADO RISK IS   POSSIBLE THIS AFTN NEAR THAT BOUNDARY...WHERE LOW-LEVEL HODOGRAPHS   AND VORTICITY SHOULD BE MAXIMIZED.

[yoda]

Pretty decent for this afternoon IMO... disco from the LWX morning AFD update:

 

PER THE 12Z IAD RAOB...LITTLE INHIBITION EXISTS THIS MORNING AND
AFTER MODIFYING THE SOUNDING FOR SOUTHERN MD... WHERE INSTABILITY
IS FCST TO BE HIGHER...NEAR 3K J/KG OF MLCAPE IS POSSIBLE.
BULK SHEAR VALUES OF 35-45 KTS ARE EXPECTED TODAY WHILE THE JET
STREAM MOVES INTO THE MID- ATLANTIC. THIS FEATURES WILL LIKELY
ENHANCE THE THREAT OF STRONG TO SEVERE THUNDERSTORMS. THERE IS
SOME WIGGLE ROOM WHERE THE COLD FRONT SETS UP EARLY THIS
AFTERNOON. AREAS ALONG AND EAST OF I-95 INCLUDING THE WATERS HAVE
THE POTENTIAL OF STRONG TO SVR THUNDERSTORMS LATE THIS AFTERNOON
AND INTO THE EARLY EVENING.

1043 AM EDT TUE AUG 4 2015

THIS HAZARDOUS WEATHER OUTLOOK IS FOR THE MARYLAND PORTION OF THE

CHESAPEAKE BAY...TIDAL POTOMAC RIVER...AND ADJACENT COUNTIES IN

CENTRAL MARYLAND AND NORTHERN VIRGINIA AS WELL AS THE DISTRICT OF

COLUMBIA.

.DAY ONE...TODAY AND TONIGHT

SCATTERED THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND EVENING.

A FEW THUNDERSTORMS MAY BECOME SEVERE...ESPECIALLY NEAR AND EAST

OF INTERSTATE 95. SEVERE THREATS ARE DAMAGING WIND GUSTS...LARGE

HAIL AND ISOLATED TORNADOES.

[high risk]

so, where will the convection initiate?    the hi-res guidance suggests that the best chances are southeast of DC, and that's where SPC has their slight risk.    I was hopeful of initiation west of I-95, and perhaps that can still happen, but dew points are coming down now at IAD and DCA, suggesting that the SPC outlook is right.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BALTIMORE MD/WASHINGTON DC
221 PM EDT TUE AUG 4 2015

.SYNOPSIS...
A SURFACE TROUGH WILL CONTINUE TO GRADUALLY SHIFT SOUTHEAST
THROUGH THE AREA TODAY. HIGH PRESSURE WILL BUILD INTO THE AREA
LATER TONIGHT THROUGH WEDNESDAY. THE BOUNDARY WILL RETURN NORTH AS
A WARM FRONT AND STALL OUT OVER THE AREA FOR THURSDAY AND FRIDAY.
LOW PRESSURE WILL RIDE ALONG THE BOUNDARY...PASSING THROUGH THE
REGION THURSDAY NIGHT AND FRIDAY. HIGH PRESSURE WILL GRADUALLY
BUILD IN BEHIND THE LOW NEXT WEEKEND.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
AN UPPER LOW IS LOCATED NEAR HUDSON BAY WHILE THE JET STREAM
ROUNDS THE TROUGH ACROSS THE GREAT LAKES INTO THE MID- ATLANTIC
THIS AFTERNOON. A SURFACE LOW IS ON THE EAST SIDE OF HUDSON BAY
WHILE A WEAK COLD FRONT...MORE REPRESENTATIVE OF A SURFACE TROUGH
IS DRAPED ACROSS THE NORTHEAST AND ALONG THE I-95 CORRIDOR THIS
AFTERNOON. A COASTAL LOW OFF MYRTLE BEACH WILL MOVE NE AND OUT TO
SEA.

THE SURFACE TROUGH HAS DIVIDED THE MID-ATLANTIC WITH DEWPTS DROPPING
ACROSS THE POTOMAC HIGHLANDS AND TEMPS IN THE MID 80S AND WARM AND
HUMID CONDITIONS EAST OF THE BLUE RIDGE WITH TEMPS IN THE UPPER 80S
ALONG I-95 AND DEWPTS IN THE UPPER 60S TO LOW 70S IN THE SOUTHERN
MD. A CU FIELD HAS FORMED ACROSS MUCH OF THE REGION AS MIXING HAS
OCCURRED. THE CU HAS A FORWARD TILT TO THEM SHOWING SHEAR IN THE MID-
LEVELS. SHOWERS AND THUNDERSTORMS ARE EXPECTED TO FORM NEAR THE
SURFACE TROUGH AXIS AND EAST WITH COVERAGE AND INTENSITY INCREASING
NEAR AND EAST OF I-95 WHERE TEMPS AND DEWPTS ARE HIGH AND
INSTABILITY IS GREATER THAN 1500 J/KG. EFFECTIVE SHEAR RANGES FROM
30-40KTS ACROSS THE REGION. A STABLE LAYER IS APPARENT ON RAP
FCST SOUNDINGS FOR S MD LEADING TO LITTLE CU FIELD ACROSS AREA OF
CONCERN...PIEDMONT AND S MD. THIS SHOULD BE OVERTAKEN THIS
AFTERNOON. THE CONVECTION FROM THE COASTAL LOW NEAR THE MYRTLE
BEACH HAS PRODUCED NORTHWARD MOVING OUTFLOW BOUNDARIES THAT MAY
REACH THE MID-ATLANTIC.

THE BEST CHANCE FOR STRONG TO SEVERE STORMS APPEARS TO BE I-95 AND
EAST INCLUDING SOUTHERN MD...TIDEWATER REGION AND SURROUNDING
WATERS. SEVERE THREATS INCLUDE DMG WINDS...LARGE HAIL AND ISO
TORNADOES.

I'm hesitant to declare it done just because of a slight DP shift.  DCA has microclimate issues obviously, but IAD has not moved much.

 

[yoda]

I think I see initiation SW of Harrisonburg

[MN Transplant]

I think I see initiation SW of Harrisonburg

 

The question is whether the cu field is suggesting initiation will be there, or is there just some minor forcing there and the game is already east of us.

True, I have been monitoring that as well...  looks like another storm is getting going along I-81 corridor... I think I-81 is the initiation zone... which is good for us

[yoda]

Storm west of Warrenton looks decent

[high risk]

  fair point.   trying to find the front, and it may indeed still be well west of I-95.

MESOSCALE DISCUSSION 1608
NWS STORM PREDICTION CENTER NORMAN OK
0248 PM CDT TUE AUG 04 2015

AREAS AFFECTED...PORTIONS OF DE/MA/VA AND SOUTHERN NJ/DC METRO

CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE

VALID 041948Z - 042245Z

PROBABILITY OF WATCH ISSUANCE...40 PERCENT

SUMMARY...AT LEAST ISOLATED THUNDERSTORMS SHOULD CONTINUE TO DEVELOP
WITH THE POSSIBILITY OF AN INCREASING SEVERE RISK THROUGH LATE
AFTERNOON/EARLY EVENING ACROSS CENTRAL/EASTERN VA AND DC METRO
VICINITY TO DE/EASTERN MD AND POSSIBLY SOUTHERN NJ. SEVERE WIND/HAIL
WOULD BE POSSIBLE.

DISCUSSION...ON THE SOUTHERN PERIPHERY OF STRONGER UPPER-LEVEL
FORCING FOR ASCENT/VERTICAL SHEAR...THUNDERSTORMS HAVE BEEN
RELATIVELY SLOW TO DEVELOP THROUGH MID-AFTERNOON WITH ONLY WIDELY
SCATTERED DEVELOPMENT...PRESUMABLY ATTRIBUTABLE TO RELATIVELY WEAK
CONVERGENCE IN THE PRE-FRONTAL WARM SECTOR VIA A PREVALENT WESTERLY
NEAR-SURFACE WIND COMPONENT. THAT SAID...THUNDERSTORMS HAVE BEGUN TO
SOMEWHAT INCREASE ACROSS WESTERN VA IN GENERAL VICINITY OF THE BLUE
RIDGE AS STRONG HEATING CONTINUES. CONVECTIVE INHIBITION IS
ESSENTIALLY NIL WITHIN A MODERATELY UNSTABLE ENVIRONMENT WITH
1500-2500 J/KG MLCAPE. WHILE MOST CONVECTION-ALLOWING GUIDANCE HAS
BEEN TOO FAST/AGGRESSIVE WITH DEEPER CONVECTIVE DEVELOPMENT THUS
FAR...IT IS STILL PLAUSIBLE IF NOT LIKELY THAT AT LEAST WIDELY
SCATTERED STRONGER STORMS WILL DEVELOP/MATURE AND SPREAD EASTWARD
THROUGH LATE AFTERNOON/EARLY EVENING ACROSS CENTRAL/EASTERN VA AND
DC METRO VICINITY OF EASTERN MD/DE AND POSSIBLY SOUTHERN NJ. WITH
40+ KT EFFECTIVE SHEAR SUPPORTIVE OF WELL-ORGANIZED
STORMS...DAMAGING WINDS AND SOME SEVERE HAIL WOULD BE POSSIBLE WITH
THE STRONGER UPDRAFTS/DOWNDRAFTS. WHILE A WATCH ISSUANCE DOES NOT
APPEAR IMMINENT AS OF 345PM EDT...LATE-AFTERNOON TRENDS WILL
CONTINUE TO BE MONITORED FOR A POSSIBLE WATCH.

Here's your MD, Yoda. https://twitter.com/NWSSPC/status/628654191322484736

 

 

As far as where the front is located... My guess is along I-81 with the winds from the W-WNW in West Virginia while the winds are out of the SW on the eastern side of the BR. We'll have to see if the storms fill in between Lynchburg and DC. 

[yoda]

2000 SPC OTLK disco for us:

 

..MID ATLANTIC THIS AFTERNOON/EVENING  

 
DEEPER CUMULUS CONVECTION HAS BEEN RELEGATED TO THE BLUE RIDGE THUS  
FAR...BUT STRONG SURFACE HEATING/MIXING SHOULD STILL ALLOW A FEW  
STORMS TO SPREAD E OF THE MOUNTAINS THIS AFTERNOON ACROSS VA.  
MODERATE CAPE AND EFFECTIVE BULK SHEAR OF 35-40 KT WILL BE  
SUFFICIENT FOR ORGANIZED MULTICELLS/SUPERCELLS CAPABLE OF PRODUCING  

AT LEAST ISOLATED LARGE HAIL AND DAMAGING WINDS.
